Z SHEETS-SHEET 2A If made 1n Lne rorm or a truncated hollow cone, as herein illustrated, the depth of the trap or disk will be about equal to or a little less than one-half the diameter of the ball, although I do not restrict myself thereto as the proper dimensions depend on the particular material or materials of which the trap or disk is made. The dimensions otherwise of the disk will also depend upon the material and the particular taste of the user, for example the outside diameter of the base will be greater accordingly as the material of which the disk is made is stiffer and the diameter of the hole will be smaller accordingly as the user desires to set himself a more diiicult task. I have used putting disks made in accordance with my invention, ing dimensions r-diameter of disk 812` inches diameter of the hole 4 inches; height ofthe inner edge of disk of an inch from the green or base, but I do not wish or intend to conne myself to `these. It will be seen that the diameter of the disk is large compared to the height thereof, and as a result the walls or sides of the putting disk have a general slope upward. This is important because it is very desirable that the walls of the disk should not present an appreciable resistance to the movement of the golf ball thereover.

If the material is not of itself waterproof or damp resistant it may be rendered to be so by any suitable known process care being exercised that no waterproofing process be employed which would seriously inter- ;flere or disturb the flexibility ofthe trap or 1s r. v

The trap or disk may be coated with enamel, paint or other material or with fabric to increase or alternatively decrease its grip on the ball or to increase or alternatively decrease its iiexibility or pliability having the follow- WMlulllluimllllau1liiaalli.1al.il.imiliiulaWMMWWMWWWWi i n Matmata i am...

and the said disk according to the material employed in its manufacture may be made by molding, stamping or otherwise.

What I claim as my invention and desire to secure by Letters Patent is 1. A putting disk for use in the practice of golf having a hollow truncated cone shapeand made of thin very pliable but resilient material, the sides of the disk having insufficient rigidity to support the golf ball whereby when al golf ball rolls onto saidvdisk the portion thereof over which the ball passes will be depressed lby the weight of the ball and lie fiat on the ground, the resiliency of the walls causing the disk to resume its normal shape as soon as the ball has passed olf therefrom.

2. A putting disk having the shape of a hollow truncated cone with the base thereof of large diameter compared with the height,

said disk being made of very pliable but resilient material whereby the disk will yield to the ground under the weight of a golf ball and will resume its normal shapeV after the ball passes off therefrom.

8. A putting disk of thin, pliable but resilient material having a central golf-ballreceiving aperture and inclined sides, the material of the disk having sufficient pli-l ability t-o yield readily under the weight of a golf ball without presenting any appreciable resistance to the passage of the ball, the resiliency of the material causing the disk to assume its normal shape after the ball passes thereover. y

` In testimony whereof I have signedvmy name to this specification in the presence of two subscribing witnesses. Y
